Résumé

Resistance to viruses is an important aspect of plant breeding. One way to achieve it is to select genetic resistances based on the susceptibility factors hijacked by the virus to infect the plants. Here, we recount work done on genes encoding translation initiation factors eIF4E, some of the most successful targets for obtaining resistance to potyviruses, starting from their characterization 20 years ago. With examples from different plant species, pepper, tomato, tobacco and arabidopsis, we present the basis of this type of resistances and their characteristics, highlighting the role of gene redundancy among 4E factors, their specificity for the virus and the need for the plant of a trade-off between resistance and development. Finally, we show how the new genome editing techniques could be used in plant breeding to develop eIF4E-based resistances in crops, mimicking the functional alleles that have been selected during evolution in many crops.
